Vertical Pleated Insect Screen
The form where the mesh moves up-down on the vertical axis — it eats none of the narrow window’s width since it carries no second profile beside it.
What Is the Vertical Form?
The vertical pleated insect screen is the window form where the mesh moves on the vertical axis — top to bottom. Closed, the mesh covers the whole opening; opened, it gathers folding to the edge.
On the horizontal arrangement the mesh gathers to one side and wants a side profile. On the vertical form the load-bearing line is at the top — no second profile column forms on either side of the opening.
Why Advantageous on Narrow Windows?
The centimetres a horizontal casing would eat come out of the narrow window’s net width — the vertical form gives no such loss; the opening width is preserved as it is.
The same axis works on roof and sloped windows too — gravity helps the movement while the tension arrangement holds the mesh at the wanted height.
Gathering Arrangements
Three gathering styles — the joinery’s reach and form state make the choice.
| Arrangement | Operation | Suited Situation |
|---|---|---|
| Top-Gathering | The mesh folds onto the top edge | Standard vertical window |
| Bottom-Gathering | The mesh folds onto the bottom edge | Railed and sloped joinery |
| Two-Way | The mesh can gather in both directions | Tall windows with limited reach |
Standout Features
The aspects of the vertical form that make a difference on narrow and sloped openings.
- Up-Down MovementThe mesh works on the vertical axis — it wants no room at the sides.
- Width PreservationNo side profile column — the narrow window’s net width is preserved.
- Shutter CompatibilityOn shuttered windows it can be installed in the gap behind the rail.
- Wind StopThe wind stop on the bottom panel keeps the mesh on the guide line.
- Double OptionWith two panels, wide vertical openings are covered in a single system too.
- Four SeasonsNo winter removal needed — it waits in the closed position.
Questions About the Vertical Pleated Insect Screen
Should vertical or horizontal be chosen?
Does the mesh drop on its own?
Does it fit a roof window?
Does the mesh come off in wind?
The casing series mounting on windows are in the product catalogue; the inside-vs-outside position decision is described on the installation types page. The window and opening types the vertical form mounts on are detailed in the application areas.
